People from several Edmonton churches shared tips on reducing their carbon footprints Saturday at a day-long workshop called Living Faithfully in Oil Country.

Sherry Ann Chapman of the Southminster-Steinhauer United Church says her church has decided to do away with Styrofoam.

"When we make our space available to people, we have the conversation about, 'We don't use Styrofoam here.' We have our recycling here. And when we're having coffee, it's always in real ceramic mugs," she said.

The church is also raising money for toilets that use less water.

Rosanne Thede, with the social justice church coalition KAIROS, led a workshop on "carbon fasts," designed to help people reduce their carbon footprint, or their negative impact on the environment.

"Partly it's becoming aware. What is our footprint as an individual? And so then taking steps on things like looking at what we eat. So how can we eat more local foods so we don't transport as much? How we do use our energy? And … when you do that environmental footprint, you can say, 'ooh, I can change in this way,'" said Thede.

She also suggested using more energy-efficient lights and going car-free.
